Our young heroes - American exchange students - and their French friends encounter unexpected experiences and adventures during the Americans’ stay in France. These stories feature exciting mystery adventures to captivate the interest of beginning French students, and offer cultural highlights interspersed throughout all four stories to acquaint readers with local customs in various areas of France. The four complete adventure stories each contain illustrations, questions, and a complete vocabulary list to reinforce structure and vocabulary taught in beginning French. Danger sur la Côte d’Azur! What an ideal place for an adventure -- the French Riviera -- with its eternal sunshine, sandy beaches, and that wonderful blue of the Mediterranean! But our friends’ summer escapades happen to lead them to the very spot of a plutonium smuggling rendezvous! And who happens to be at the rendezvous? Their host, Monsieur Cau. Is this man a spy, a foreign agent involved in smuggling atomic products? What happens to him depends entirely on the skill of our young friends.
